A clarification about scoring

From the office of Sen. Tom Harkin, Kate Cyrul writes:

There’s been a bit of confusion over the cost of our bill, so I wanted to let you all know that CBO released two scores yesterday. We are scoring against the March 2007 baseline, revised to reflect the enactment of the energy bill and omnibus appropriations bill late last year, so our bill is $288.97 billion over 5 years.
